JOHN \V. VAN DYKE, OF BROOKLYN, NEW YORK.

WATER-TUBE BOILER.

SPECIFICATION forming part of Letters Patent No. 315,189, dated April 7,1885.

Application filed July 16, 1884. (No model.)

To all whom it may concern.-

Be it known that I, JOHN W. VAN DYKE, of the cityof Brooklyn, county ofKings, and State of New York, have invented a new and useful Improvementin ater-Tube Boilers or ater-Heaters, of which the following is a full,true, and exact description, reference being had to the accompanyingdrawings.

In this application when I use the word pipe I refer either to what areknown as pipes or tubes in the trade. By this invention Iarrange mypipes in headers, which consist of a series of chambers, each containingtwo pipes arranged on the same or nearly the same horizontal plane. Inthe previous structures of this class the pipes have been arranged inheaders over each other, so that the circulation of the water has beenfrom a pipe beneath, through a chamber, and into a pipe above. By thisarrangement the circulation of water is from one pipe through a chamberto another pi pe immediately adjacent thereto. That which is new in myinvention will be found pointed out in the claims hereto annexed.

In my drawings similar letters refer to similar parts.

Figure 1 represents a general vertical elevation of my boiler. Fig. 2represents an end view, partly in section, with the covers of mycirculating-headers removed. Fig. 3 represents a back View of the same.Fig. 4 represents a horizontal section through Fig. 1 on the line 1 i,and Fig. 5 represents a section through Fig. 1 on the line an. Figs. 6and 8 represent a view of a modification of my header. Fig. 7representsa view of the header shown in Fig. 3, with the tubes inposition. Fig. 1 is taken partly in section on the line 9 g of Fig. 2.

-In the drawings, A represents the pipes connecting the headers ateither end of the boiler. In the form shown these pipes A are arrangedin two series, the lower one being marked A. The water enters the seriesA through the stand-pipes a, (shown in Fig. 3;) thence the water passesinto the horizontal open header 1); thence it passes into the series oftubes marked 1 in the drawings. The pipes 1 enter the horizontal header0, (shown in Fig. 2,) which header consists of a series ofcirculating-chambers arranged horizontally, each chamber containing twopipes which are at' or about the same horizontal 1evel.- The waterentering by the pipes 1 passes into the pipes 2; thence through chambersin the horizontal header d to pipes 3; thence through chambers in thehorizontal header 6 to pipes 4; thence through chambersin the horizontalheader f to pipes 5. The other end of the pipes 5 enters the continuousopen header 9. The open header communicates with the stand-pipes B,which communicate with the drum 0, which constitutes the steam-space ofthe boiler. The stand-pipes a and B both connect with the bottom of thedrum C at the different ends thereof. The grate -bars are shown at D,and the products of combustion are compelled to travel through acircuitous path to the chimney E by means of deflectors F F, which maybe preferably made of fireof pipes, leaving openings at either end, as

proof material laidtransversely upon the rows shown. Ifdesired,theheaders maybe arranged with the pipes one a little above theother to increase the circulation; but this is not essential. Thisarrangement is shown in Figs. 6 and 8. As many of these series ofindependent circulating-sections may be employed as is desired. Asshown, two are used. Any number of circulating-pipes may be employed ineach series, or but one series may be employed in certain instances.

The advantage in breaking the pipes up into series is, that a more rapidcirculation is obtained by delivering from and into large openstand-pipes through a short series than would be obtained by forcing thewater or steam through the entire series of pipes.

It will be obvious that the arrangement of these pipes can be somewhatvaried without departing from the spirit of my invention, the novelty ofwhich consists in the peculiar horizontal circulation herein shown. Itwill be seen that by this arrangement a very compact structure can bemade, the tubes lying close together in horizontal planes instead ofbeing separated vertically. The deflectors F F are not essential.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. The combination,with two or more horizontal headers arranged ateither end of a boiler or steam-generator, each of said horizontalheaders having chambers, each chamber containing two openings at ornearly at the same horizontal plane, of pipes connecting each headerwith a header at the other end of the boiler, arranged at a higher leveling divided by vertical partitions into chambers, each chambercontaining two openings at or nearly at the same horizontal plane, ofpipes connecting each header with headers at the other end of theboiler, arranged at higher and lower levels than the first header, andwith the connections shown, whereby the water is caused to circulatehorizontally, or near- 1y so, through each header-chamber, and thenthrough a pipe to the opposite header at a higher level than the firstheader, and thence horizontally through the second header-chamber, andthrough a pipe returning again through the heatingspace, substantiallyas described.
